Diesel Testers has served the Permian basin and West Texas for nearly half of a century. We were founded we are owned and we are operated by native Texans, we understand the oil and gas industry as well as the ag business, and we are in our work for the long haul, committed to doing the job right the first time, and with a combined experience that spans nearly a century and a half of knowledge and expertise.

Plainly stated, we love diesel engines, we also love natural gas engines, and everything to do with turbo chargers and fuel injection systems that support these awesome machines. But we are not just enthusiasts; we are a group of factory trained and authorized technicians and practitioners, and hold long-standing memberships with the prestigious Association of Diesel Specialists.

We are not just a service center and installation service, we are also factory rebuilders for many brands, and have a friendly relationship even with our competitors, who often bring us work when they find themselves overwhelmed with the complexity or difficulty of the task. For every job we undertake, over half of the work that we do involves diagnostics; we don't simply wade into a task without combining our considerable expertise with expert knowledge, and state of the art technology to assure a job well done, a job perfectly done and a job finally done.

We are as honored to have YOU as a customer as we were honored to have our first customer all those years ago, we have not forgotten our roots, we are ready for the future, and we are privileged to do business with you, please be in touch, Thank You, and God Bless Texas!
